Crafting a Scout specific hat with 4 refined and a scout token my provide you with a high chance of a bonk helm!

im sure there's an option in the advanced crafting to craft the bonk helm.

I am unsure if using a Bonk! and four refined is going to give you one for sure and going for a batter's helmet with the current price of it is hard. So currently trying to craft it with four refined seems to be the best bet.
